Systems and methods for air flow circulation are described which utilize one or more air conditioning units as well as transfer grilles to move cooler air from one space to another. The transfer grilles can include bi-directional in-line fans to move air between spaces in discrete ducts located between the spaces. Motorized dampers can be controlled by a controller that receives information about various rooms and areas from temperature and occupancy sensors within those rooms or areas. In this manner, conditioned air can be directed to those rooms that are occupied and whose temperature needs correction based on a thermostat setting, and use of the air conditioning unit can be avoided when a cool air source is present in another space.

A heating, ventilation, and air conditioning (HVAC) system may be zoned into one or more zone. The HVAC system may include HVAC components, sensors, and one or more register vents that may include vent dampers (e.g., electronically controllable vent dampers or manually operated vent dampers). Opening and closing of the vent dampers may facilitate creating zones or sub-zones in the HVAC system configuration. An HVAC control system may receive a request for conditioned air in one or more of the zones, determine a damper setting for at least one of the vent dampers, communicate the determined damper setting to a vent damper or user interface, determine which HVAC components should be active, if any, and/or provide controls signals to activate or keep active the HVAC components that are determined to be active.

An air-conditioning system includes a refrigerant system in which an outdoor unit, one or more indoor units, and one or more ventilators are connected by a refrigerant pipe and in which refrigerant circulates, and a control device configured to control the refrigerant system. The control device includes a target temperature adjustment unit configured to adjust a target evaporating temperature based on a detection value detected by a temperature and humidity detection unit provided to at least one of the indoor unit and the ventilator that satisfies a specific criterion, and an air-conditioning control unit configured to control the refrigerant system such that the evaporating temperature of each of the indoor unit and the ventilator is equal to the target evaporating temperature adjusted by the target evaporating temperature.

A building system for a building including one or more storage devices storing instructions thereon that, when executed by one or more processors, cause the one or more processors to operate one or more pieces of building equipment associated with a building space based on a first operating mode. The instructions cause the one or more processors to receive an indication to update operation of the building space based on an emergency situation and responsive to receiving the indication to update operation of the building space based on the emergency situation, operate the one or more pieces of building equipment based on a second operating mode, wherein the second operating mode defines one or more second parameters for the one or more pieces of building equipment and is adapted to reconfigure the operation of the building space to address or mitigate the emergency situation.
